I want to launch a straightforward yet reliable mobile finance tracker that works identically on iOS and Android. The core idea is to let users record income and expenses on the go, view daily and monthly summaries, and export data to CSV for personal backup or tax prep. A cross-platform framework such as Flutter or React Native feels like the fastest route, but if you have a stronger approach I’m open to hearing it. Clean, readable source code and an intuitive UI matter more to me than a long feature list, so keep the design lean and the navigation familiar to regular banking apps. When you send your bid, focus on the relevant mobile experience you already have—especially anything around personal finance, data visualisation, or secure local storage. Screenshots and store links help me gauge quality quickly; no need to paste generic résumés. Deliverables • Production-ready iOS and Android builds, published to TestFlight / internal testing track • Full source code with brief setup instructions • A short hand-off call or video walkthrough so I can maintain the project going forward If this sounds like a good fit, tell me how you’d tackle the sync, export, and privacy pieces, and roughly how long you expect the build to take.
